Fig. 1.


Observed lines of the new molecule found in the 31–50 GHz domain towards TMC-1. The abscissa corresponds to the local standard of rest velocity in km s−1. Frequencies and intensities for the observed lines are given in Table 1. The ordinate is the antenna temperature corrected for atmospheric and telescope losses in mK. The J = 19 − 18 line is only detected at a 3.5σ level. Spectral resolution is 38.1 kHz.
